# Choreography Microservices

Event-Driven Microservices with Kafka and Choreography as the consistency pattern

## Why

This was a laboratory for the High-Potential Technical Booster hosted at EDEM and sponsored by Capgemini

### Source

### Reference

## Data Flow

```mermaid

flowchart LR;

    shop_order[Shop Orders]-->|OK|stock[Stock];

    stock-->|KO|shop_order;

    stock-->|OK|payment[Payments];

    payment-->|KO|stock;

    payment-->|OK|shipment[Shipments];

    shipment-->|KO|payment;

    shipment-->|OK|invoice[Invoices];

    invoice-->|KO|shipment;

    invoice-->|OK|shop_order;

    shop_order-->|KO|notification[Notifications];

    shop_order-->|OK|notification;

    notification-->a("Send Notification");

```

## Structure

- scripts, e2e testing

- server, kafka and zookeeper, WIP

- src, microservices

## Language Philosophy

Trying not to default to Java, each microservice is written in a different language

- Ruby -> shop_orders

- C# -> stocks

- Golang -> payments

- PHP -> shipments

- Python -> invoices

- Node -> notifications

## Testing

Each microservice owns their own testing strategy.

The payloads are defined in the microservice, as a json file

There's a root script to execute every single e2e testing of each microservice in order

## Handlers

```java

class ServiceHandler {

    public ShopOrderRequest shopOrderRequest;

    // ...

    public void success() {

    }

    public void fail() {

    }

    public void process() {

    }

}

```
